Any suggestions for strong vibrators?

My personal store is dedicated to strong vibrators made from safe materials. I'm curious if anyone has suggestions for toys I should add. You can check out what I'm already carrying here and let me know what you think I'm missing!

Uma is a hair stronger than Mimi. So that should meet your classifications.

The Spirit is stronger than the Seed but not as strong as Mimi. I'm not sure exactly how strong you want it to be to classify as "strong."

Basically, my test for "strong" is if it can get me off! The Seed does absolutely nothing for me, and MiMi works most of the time. If Spirit is weaker than MiMi is might not be enough, but I'd still like to try one of the Leafs. I wonder if any of them have more power.

They are all powered by the same motor, as per my understanding. But I guess we will see with the reviews.
